- EYEGLASS-MOUNTING.

SPECIFICATION forming part of Letters Patent No. 775,956, dated November29, 1904.

Application filed July 30, 1904. Serial No. 218,880. (No model.)

To all zbhont it may concern:

Be itknown thatI, SANFORD E; Wns'r, a citizenof the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements inEyeglass-Mountings, of which the following is a specification, referencebeing had therein to the accompanying drawings.

Like letters indicate like parts.

Figure 1 is a plan View of the blank from which my improved eyeglassmounting is made. Fig. 2 is a rear elevation of a pair of eyeglassesprovided with my said invention. Fig. 3 is a sectional detail view asseen on line m w of Fig. 2. Fig. 4 is a plan view of the said blank withcertain modifications. Fig. 5 is a rear elevation of a pair ofeyeglasses provided with my improved mountings adapted to be easilyattached to and detached from the lenses. Fig. 6 is a sectional detailview as seen on line y y of Fig. 5.

My invention relates to the mountings of eyeglasses; and it consists ofthe novel construction and combination of the several parts, ashereinafter described, and specifically set forth in the claims.

My invention is a one-piece eyeglass-mounting comprising two guards, twolens-straps, and a bow-spring or nose-piece, all made of a single pieceof metal. It is especially designed for use upon rimless eyeglasses, butmay be modified to adapt it to eyeglasses whose lenses are fitted ineye-wires.

In the drawings, A B are the lenses, each of which near the inner end isprovided with a hole or aperture, as seen at a in Fig. 6.

In Fig. 1 is shown the blank from which my said improvedeyeglass-mounting is formed by proper bending. This blank is athin pieceof sheet metal, preferably of gold or goldplated stock and cut in thepeculiar shape illustrated in said figure. It is oblong and has its twolarger edges substantially parallel to each other. Each of its two endsis formed with a series of three semicircular scallops, at theconverging ends of which, respectively, are two short cuts parallel withthe longer edges of the blank, as shown at I) and c. There is a cutindicated at (Z, which is in line with the two cuts 7) 7), but whichleaves a solid portion a between its ends at the adjacent cut 7). Thereare two short cutsf'f' in line with the cuts 0 0, respectively,extending inwardly from the solid portions 0 a, respectively. There areformed the apertures or openings 9 g and the centrally-located openingsh. Thus there are provided the following parts, all integral, butcapable of bending each in its own proper direction: C, the nose-piece,bow-spring, or bridge; D, the upper lip for lens A; E, the upper lip forlens B; F, the inner strap for the lens A; G, the outer strap for lensA; H, the inner strap for lens B; I, the outer strap for lens B; J, thelower lip for lens A; K, the lower lip for lens B; L, the guard for lensA, terminating in the oval plate M; N, the guard for the lens B,terminating in the plate 0. The outer end of the strap F has thescrew-hole a, and the free end of the strap G- has the beveled hole j,adapted to receive a screw, Figs. 1 and 3. In like manner the outer endof the strap H has the screw-hole 7c, and the free end of the strap Ihas the beveled hole Z for the reception of a screw-head. The forms andshapes given to this blank by bending and its connection with the lensesare shown in Figs. 2

and 8. In Fig. 2 the portion C of the blank from one solid portion orcross-bar to the other solid portion or cross-bar has been bent, as seenat a and 0, into the long partial oval bow g). The lips D and J havebeen bent to lit on the inner edges of the lens A. The strap F has beenbent to lie against the inner face of the lens A. The strap G has beenbent to lie against the outer face of the lens A, Fig. 3. The portion Lhas been bent at g and 7, and the plate M. has been bent to fit the noseto form the guard. The lips E and K have been bent to fit on theinneredge of the lens .13. The strap H has been bent to lie against the innerface of the lens B. The strap I has been bent to lie against the outerface of the lens B. (Not shown, but similar to the position of the strapG on lens A, seen in Fig. 3.) The portion N has been bent, as seen atsand t, and the plate 0 has been bent to form the guard to fit thenose.A screw P, passing through the holes j and v'of the straps F and G andthrough the hole of the lens, as E made therefor, and fastened byscrews. The

seen in Fig. 3, clamps the straps F G and lens A together, and so ascrew Q similarly clamps the straps H and I to the lens B. i

The blank shown in F igML is in all respects like that shown in Fig. 1,except that it has the four holes nu o '2), and instead of the holes 2'jk Z it has the four teats 2 z 2 The strap G has an inward bend (bestshown in Fig. 6) constituting a concave seat, as illustrated at R. Alocking-lever S of approximately a right-angled triangular form (withrounded edges at each end of its hypotenuse) is mounted on a pivot T,which passes through the holes a u. The inner rounded end of this leverS constitutes a camsurface, as the pivot T is nearer the rightangledcorner of the lever S than it is to the rounded inner corner of saidlever. Hence when the lever S is in the position indicated by dottedlines in Fig. 6 the resilience of the straps F and Gr causes the endsthereof to spread somewhat apart, and then the points of the teats 2 2are sufficiently separated to allow the insertion of the lens A betweenthem. Then when the hole a of the lens A and the points of the teats zare in alinement the lever S is moved from the position shown in dottedlines in Fig. 6 to the position shown in solid lines in said figure, bywhich movement the cam-surface of the lever S, pressing against the seatR of the strap Gr, forces the strap Gr inwardly, thereby causing theteats z 2 to enter the hole a of the lens A, as illustrated in Fig. 6,and so to clamp the straps F G upon the lens A. By moving thelocking-lever S in the direction indicated by the arrow in Fig. 6 thestraps F G are enabled to spring apart by their own resilience and sothe lens A can be detached therefrom. A similar locking device isprovided for the straps for the lens B, comprising a lever S, mounted ona pivot T; By reason of this locking device the clamping screws P Q,(shown in Fig. 2) are dispensed with, and it is easy to attach theeyeglass-mountings to the lenses or to detach them therefrom.

It has been common heretofore to use posts (which are attached to thelenses by straps and screws or by eye wires or rims) and to these poststo fasten by means of screws the spring bow or bridge and also theguards. By my improved construction the parts 6 e, the bends of theblanks between the lips D J, and the inner portions of the straps F Gserve the purpose of the post and by the several bends are made veryrigid and strong. The bow and the guards being integral therewith do notrequire any screws or other fastening. This device is much cheaper thanthe usual construction, more easily applied, and better adapted forsecuring accurate adjustment than in the eyeglass-mountings of the usualkind.

The guards are commonly separate pieces secured to the post, generallyin channels guards are especially selected for each person and aretherefore made in different shapes, some to extend upward, somedownward, and some at various angles. These must be carefully selected,and if when tried they do not fit, or feel uncomfortable, they areremoved and another pair is chosen and fitted. In the use of myinvention no selection is necessary. Any one of my improved devices isadapted to be used in any case. The portion L (N) constitutes the shankof the guard-plate M (O) and can be easily bent by pliers in anydirection, up or down, in or out, or are twisted to any desired extent.The guards are shown in the drawings as bent upward; but, if desired,they can as well be bent downward and be made to take any angulardirection which may be necessary to insure a comfortable fit.

A rubber pad or piece of cork, xylonite, or other suitable material maybe secured to the plate M (O) to provide a wearing-surface in contactwith the flesh.

It is obvious that the bow and posts may be made integral without theguards or that the post and guards may be made integral without the bowor that the posts, straps, and bow may be integral without the guards orthat the post, straps, and guard may be made integral without the bow orthat the bow and guards may be made integral without the posts andstraps; but these variations are within the scope of my invention andembody the principles thereof.

I claim as a novel and useful invention and desire to secure by LettersPatent- 1. The improved blank for an eyeglassmounting herein described,consisting of a single sheet of metal, comprising the end pieces D, F,J, E, H, K, separated by the straight cuts 6, 0, b, a, the centralportions C, G, L, I, and N, separated by the straight cuts (Z, (Z, f,the cross-bars e, e, and the plates M, O, at the inner ends of theportions L, N, respectively, substantially as specified.

2. In an eyeglass-mounting, the combination of the following parts allmade from one piece of metal: a bow-spring and two upper lens-lips allof equal width throughout their entire extent and in one plane, twonose-guard shanks and two lower lens-lips all of equal width throughouttheir entire extent, said lower lens-lips being in one plane and saidshanks made each with a twist less than ninety degrees in extent, anose-guard on each of said shanks, and two U-shaped lens-straps whosefree ends are of equal length and extend in parallel planes which are atright angles to the first-named plane, substantially as specified.

3. In an eyeglass-mounting for a lens having a hole through it, thecombination therewith of a post having two straps which are resilientand are each provided with a teat adapted to enter said hole in thelens, and means for pressing and holding when compressed said straps soas to engage said lens by said teats and thereby to clamp the lens inposition, substantially as specified.

4:. In an eyeglass, the combination of a lens having a hole through it,a post, two straps extending from said post and having teatsrespectively adapted to engage said lens in the hole thereof on oppositesides, and means adapted to clamp said straps to the lens and to detachsaid straps from the lens, substantially as specified.
